Original publication and holotype designation: Carter, H.J. (1865). On the fresh- and salt-water Rhizopoda of England and India. Annals and Magazine of Natural History, series 3 15: 277-293.

Description: Unicellular, uninucleate and quadriflagellate algae devoid of cellulosic cell walls. Cell shape variable but mostly obovoid to ellipsoid. Lateral margins somewhat angular with a broad, truncately-rounded apex, narrowing to the posterior which may bear 1-3 lobes or be simply broadly rounded. Cell posterior often pseudopodial. Nucleus typically posterior. Cells without chloroplasts and stigmata. Cytoplasm heavily vacuolate with two or more contractile vacuoles. Asexual reproduction by cell division; sexual reproduction unknown.

Gender: This genus name is currently treated as neuter.

Most recent taxonomic treatment adopted: Masjuk, N.P. & Lilitska, G.G. (2011). Dunaliellales. In: Algae of Ukraine: diversity, nomenclature, taxonomy, ecology and geography. Volume 3: Chlorophyta. (Tsarenko, P.M., Wasser, S.P. & Nevo, E. Eds), pp. 152-157. Ruggell: A.R.A. Gantner Verlag K.-G..

Comments: Collodictyon has two well-described species, C. tricellatum H.J.Carter and C. sparsevacuolatum Skuja reported from freshwater in Europe and the United States. C. hongkongense Skvortzov is inadequately described. The assignment of the marine C. sphaericum R.E.Norris to Collodictyon was questioned by Ettl.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
